networkctlsystemdnetworkctl1networkctlQuery the status of network linksnetworkctlOPTIONSCOMMANDLINKDescriptionnetworkctl may be used to introspect the
state of the network links as seen by
systemd-networkd. Please refer to
systemd-networkd.service8
for an introduction to the basic concepts, functionality, and
configuration syntax.CommandsThe following commands are understood:listPATTERN…Show a list of existing links and their status. If one or more
PATTERNs are specified, only links matching one of them are shown.
If no further arguments are specified shows all links,
otherwise just the specified links. Produces output similar to:
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
2 eth0 ether routable configured
3 virbr0 ether no-carrier unmanaged
4 virbr0-nic ether off unmanaged
4 links listed.The operational status is one of the following:

IP address, configured DNS servers, etc. If one or more PATTERNs are
specified, only links matching one of them are shown.When no links are specified, an overall network status is shown. Also see the option
.Produces output similar to:
● State: routable
Online state: online
Address: 10.193.76.5 on eth0
192.168.122.1 on virbr0
169.254.190.105 on eth0
fe80::5054:aa:bbbb:cccc on eth0
Gateway: 10.193.11.1 (CISCO SYSTEMS, INC.) on eth0
DNS: 8.8.8.8
8.8.4.4In the overall network status, the online state depends on the individual online state of all
required links. Managed links are required for online by default. In this case, the online state is
one of the following:
unknownall links have unknown online status (i.e. there are no required links)offlineall required links are offlinepartialsome, but not all, required links are onlineonlineall required links are onlinelldpPATTERN…Show discovered LLDP (Link Layer Discovery Protocol) neighbors. If one or more
PATTERNs are specified only neighbors on those interfaces are shown.
Otherwise shows discovered neighbors on all interfaces. Note that for this feature to work,
LLDP= must be turned on for the specific interface, see
systemd.network5 for
details.Produces output similar to:

Capability Flags:
o - Other; p - Repeater; b - Bridge; w - WLAN Access Point; r - Router;
t - Telephone; d - DOCSIS cable device; a - Station; c - Customer VLAN;
s - Service VLAN, m - Two-port MAC Relay (TPMR)
1 neighbors listed.labelShow numerical address labels that can be used for address selection.
This is the same information that
ip-addrlabel8
shows. See RFC 3484
for a discussion of address labels.Produces output similar to:

::1/128 0deleteDEVICE…Deletes virtual netdevs. Takes interface name or index number.upDEVICE…Bring devices up. Takes interface name or index number.downDEVICE…Bring devices down. Takes interface name or index number.renewDEVICE…Renew dynamic configurations e.g. addresses received from DHCP server.
Takes interface name or index number.forcerenewDEVICE…Send a FORCERENEW message to all connected clients, triggering DHCP reconfiguration.
Takes interface name or index number.reconfigureDEVICE…Reconfigure network interfaces. Takes interface name or index number. Note that
this does not reload .netdev or .network
corresponding to the specified interface. So, if you edit config files, it is necessary to call
networkctl reload first to apply new settings.reloadReload .netdev and .network files.
If a new .netdev file is found, then the corresponding netdev is created.
Note that even if an existing .netdev is modified or removed,
systemd-networkd does not update or remove the netdev.
If a new, modified or removed .network file is found, then all interfaces
which match the file are reconfigured.OptionsThe following options are understood:Show all links with status.Show link statistics with status.Do not ellipsize the output.When used with status, controls the number of journal lines to show,
counting from the most recent ones. Takes a positive integer argument. Defaults to 10.Exit statusOn success, 0 is returned, a non-zero failure code otherwise.See Alsosystemd-networkd.service8,
